If you don't want any user to change the wallpaper in Windows, you can edit the following registry key:-

Open Registry Editor.
Navigate to key HKCU \ Software \ Microsoft\Windows \ CurrentVersion \ Policies
Check if key named System exists. If not create new key value and name it System.
In right hand pan create a new DWORD value and name it NoDispBackgroundPage.
Double click on NoDispBackgroundPage and enter 1 as its value.
Close Registry Editor.
Now Right Click on Desktop and choose Properties. Notice the Background tab is missing preventing the change of Desktop Wallpaper.

To enable the Background Tab in Display properties change the value of NoDispBackgroundPage to 0.

If you don't want any user to change any of the display settings e.g. wallpaper, screen saver etc.; there are three ways to do it:-

Use TweakUI
On Control Panel tab uncheck the box against desk.cpl - Display Settings. This will remove Display applet from Control Panel. User can still access it through Desktop Properties.

Edit CONTROL.INI - same effect as using TweakUI
Launch Notepad or any other text editor.
Open CONTROL.INI file located in windows folder.
Check if section named [don't load] exists; if not move to the top of file and type:-
[don't load]
desk.cpl=no

This will remove the Display Icon from Control Panel.
Editing the Registry
Launch Registry Editor
Navigate to key HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Policies
Check if key named System exists. If not create new key value and name it System.
In right hand pan create a new DWORD value and name it NoDispCPL.
Double click on NoDispCPL and enter 1 as its value.
Close Registry Editor.
Now whenever user selects Display Icon in Control Panel or selects Desktop Properties, an error message "Your system administrator disabled the Display control panel" pops up.

To enable the Background Tab in Display properties change the value of NoDispCPL to 0.
